DOUBLE CONTROL FOR ROAD-ROLLER SCRAPER. ATTACHMENTS.

Application filed October 24, 1923. Serial No. 670,494.

To all whom t may concern:

Beit known that we, WILLIAM T. BEATTY, FRANK S. DAVIS, and FRED D.WILSON, citizens of the United States, residing, re-

spectively, at Flossmoor, Homewood, and

Harvey, in the county of Cook and State of Illinois, have invented acertain new and useful Improvement in Double Controls for Road-RollerScraper Attachments, of which the following is a specification.

This invention relates to road roller maintainers of the general typeshown in our earlier application, 'Serial Number 610,345, filed January2, 1923, in which a road rolling machine is equipped with a transversemaintainer or 'scraper capable of working upon the surface of the roadsimultaneously with the rolling thereof.

The principal object of this invention is 'to provide a single mechanismunder the control of an operator riding upon the roller which is notonly capable as iln said prior application of raising and lowering theentire maintainer as a unit with reference to the roller and the roadover which the inachine travels; but which is capable of selectivemanipulation to independently control the height of at least one end andpreferably botli ends of the maintainer blade.

The\invention `consists in mechanism capable oil` attaining theforegoing /and other objects; which can be easily and cheaply made ;ywhichl is satisfactory in use and is not readily liable to get out oforder. More particularly, the invention consists in various features anddetails of construction which will be hereinafter more fully set forthin the specification and claims.

Referring to the drawings in which like numerals desi ate the same partsthroughout the severa views:

Figure l is a side elevation of a road roller maintainer machineequipped with the mechanism of this invention in its preferred form.

Fivure 2 is a view of the opposite side of Figure 1, showing theextended side of` the blade. (See arrow 2, Fi 3.)

Figure 3 is a plan view o the mechanism of Figure 1.

Figure 4 is a front viewof the machine taken on the irregular line 4 4of Figure 3.

Figure 5 is a sectional, detail view on the Iline 5-5 of Figure 1.

Figure 6 is a detail of the gearing used in the maintainer elevatormechanism, appearing in the upper lef-t hand portion of Figure 1.

Figure 7 is a detail plan Vvie-W on the line 7 7 of Figure l of a formof mechanism by which the operator may selectively elevate either theent-ire maintainer blade or one end thereof.

Figure 8 is a corresponding plan view of an alternative construction bwhich the operator may selectively manipulate one mechanism to elevateor depress the entire maintainer mechanism or either selected endthereof.

The drawings show a road roller engine frame 10, carried onrear rollers12 and a front roller mechanism 14, in the particular case hereillustrated, two aligned rollers mounted on the same axle 16 inside ayoke 18 journalled on a vertical shaft 20 entering the arched member 22on the frame 10. A11 operator occupying a vseat 24 at the rear ofthemachine can turn the vertical shaft 20 and consequently the roller 14 byproperly manipulating an adjacent hand Wheel 26 on a shaft 28operatively connected through gearing 30-32 to a segmental gear 34secured to shaft 20 by any suitable means as key 36.

The conventional roller mechanism just described is equipped Wit-h a.U-shaped maintainer frame more fully described and claimed in saidprior application comprising parallel side members 38 and 40 lying onopposite sides of roller 14 and a transverse cutting or maintainer blade42 ca.- pable of angular adjustment between the full line and dottedline positions of Figure 3 through the agency of adjusting bolts 44cooperating holes 46 therefor and removable braces 48'. This frame is,as in said prior application, secured about. the roller 14 and onmovement yof the roller pushed or pulled along the road through theagency of diagonal brace members 50 and 52 adjustably attached to thebody 10- of the roller through any suitable means as, for instance, setscrews or bolts 56 selectively insertable in holes 58 or 60, as thevcase may be, provided for them in the regg apeoaeee spective members 52and 50. As fully set forth in said rior application, the further end ofeach iagonal brace rod and 52 is engaged by a downwardly movable rod 62provided with a cushion spring mechanism 6a with the result that eachadjacent side member of the lll-shaped maintainer frame and consequentlythe blade 4:2 is pressed rmly upon the ground. rlhe mechanism forexerting this pressing action on these rods 62 and conversely forelevating them constitutin a principal feature ot this invention wil nowbe described. l

'lhe upper end of the rod 62 on the lett hand side of the machine asviewed in Figure 4 is pivotally attached at 66 to a lever arm 68 carriedby a shaft 70, journalled in a bracket 71 provided for it, extendingacross the machine.

rl`he right hand end ot the bracket 71 as viewed in Figure 4 has rigidlysecured to it by any suitable means. as, for instance. bolts 72, a gearhousing 74 carrying two parallel segmental gears 76 and 78, the formerrigidly secured to shaft by any suitable means as, for instance. a key80, the latter freely rotatable on said shalt 70. lournalled on theright handend of shaft 70, as viewed in Figure Il, is a Vlever arm 82,resembling in outward appearance lever 68. heretofore referred to, anddetachably pivotally connected to the right hand rod 62 by any Suitablemeans as a pin 84C. The hub 86 of lever 82 and the hub 88 ot' segmentalgear 78 are detachably connected together around an intervening portion90 of the gear housing wall by means of suitably disposed lugs 92 and 94and interconnectin bolt 96 (see Figure 5).

Extending through the gear housing 7-1 and suitably journaled in itsopposite walls are parallel shafts 98 and 100 carrying, respectively,worms 102 and 101i meshing. respectively, with segmental gears 76 and78. ln the specific form of the invention shown in Figure 7, inwhich-the operator can selectively elevate or depress the entire main-`tainer or elevate or depress one end of the blade 4:2, in the particularcase `v`here illustrated, the right hand end as viewed in Figure 4,shait extends back to a point iii proximity to the drivers seat 24 andthere carries a single wheel 106. Slidably mounted. upon this shaft 100and readily manipultab e by hand lever 108 adjacent to the drivers seatis a connecting sleeve 110 attached to a gear 112 mounted for limitedreciprocation along shaft 100 but prevented from rotation thereon by anysuitable means, as for instance, a spline connection 114. rll`his gear112 meshes with corresponding gear 116 rigid on shaft 98 and the limitsot movement along the spline connection 114 are such that the operatorcan by properly manipulating handle 108 cause the gears 112 and 116 tomesh as shown in Figure 7, or can move gear 112 along shaft 100 until itis entirely out of mesh with gear 116. l/Vhen the gears are in meshasshown in Figure 7, rotation of hand wheel 106 will cause bothsegmental gears 76 and 78 to move in unison and will consequentlysimultaneously elevate or depress rods 62 and consequently the entiremaintainer mechanism. When gear 112 is out ot' mesh with gear 116, thefriction in worm 102 locks shaft 98 and consequently that part of themaintainer mechanism attached thereto; while rotation of shaft 100manipulates segmental gear 78 to, at `the will of the operator, raise orlower the right hand end ot the maintainer blade 42 as viewed in Figure4l.

ln the alternative construction, shown in Figure 8, shaft 98 isaccording to the drawings equipped with a slightly wider gear 120,replacing gear 116. Shaft 100 as before extends to the drivers seat 24and is there equipped with a hand wheel 106. 'l` he mechanism 110*112.of Figure 7 is removed and in this construction replaced by alongitudinally reciprocable sleeve 124 carrying rigid thereon near handwheel 106 another hand wheel 126. Rigidly secured to the opposite end ofthis member 124 by any suitable means as bolt or screw 128 is a clutchmember 130 provided with clutch teeth 132 inter-fitting with otherclutch teeth 134 on another clutch member 136 rigidlyl secured to shaft100 by an)T suitable means as, for instance, a pin 138. Rigid on clutchmember 130 is a gear 140 meshing with gear 120. Wheel 128 and parts1244-130 and gear are sldable lengthwise of shaft 100 between theposition shown in Figure 8 and a position to the leftthereof in whichclutch teeth 132 intertit with clutch teeth 13-1` Aand thus lock theseparts on shaft 100.

When the parts are in the position shown in Figure 8 and theoperator?manipulates hand wheel 106. he causes shaft 100 torocksegmental gear 78 to thus manipulate up or down as the case may be theright hand end of the maintainer as viewed in Figure 4. `When, under thesame conditions. the operator rotates wheel 126, `he causes gear 140 torotate gear 120 and consequently through the parts attached thereto rocksegmental gear 76 to raise or lower. as the case may be, the lett handend of the maintainer as viewed in Figure 4. When the operator takeshold of the handle 126 and shoves the gear 140 to the lett, as viewed inFigure 8.

until clutch teeth 132 and 13d intermesh.l

then manipulation of either hand wheel 106 or 126 will cause gears 140and120 to rotate in unison thus moving Asegmental gears 76 and 78 inunison thus raising or lowering as the case may be the entiremaintainer.

From the foregoing, it will be seen that IIL'.

by installing the mechanism of Figure 7 the operator on (seat 24 can bythe Imanipulation of a. single hand wheel and shaft selectively raise orlower the entire maintainer or raise or lower a given predetermined endthereof; and that, by the use of the mechanism of Figure 8 still carriedby a single shaft extending forward from the operators position, theoperator can at will by rotating that one shaft or mechanism journaledthereon raise or lower the entire maintainer or raise or lower eitherend thereof. By the use of these simple, readily v installed mechanisms,the operator on seat 24 has absolute control of the maintainer blade 42at the front of the machine to make the road or other surface workedupon as desired.

The maintainer mechanism described is held against lateral movement withreference to the roller frame by a transverse rod 140 and' rattling ofthe parts is prevented by a cushion spring 142 adjustably held in placeby any suitable means as, for instance, lock nut mechanism 144.

Manipulation of the maintainer frame as described is materiallyfacilitated by the use of oppositely disposed cushion springs 15()- and152 attached at their lower ends to suitable points on the maintainerframes and at their upper ends to. short lever arms 154 or 156, as thecase may be, extending on the opposite side of-shaft 70 from therespective lever arms 68 and 82.
